Our response to a global pandemic was a disaster other than getting the vaccines made. The most recent large scale collective effort to defeat an existential threat prior to that was probably WWII. We’ve gotten pretty good at waging war but I fear that’s probably where our evolution in the matter of dealing with existential threats will probably remain.

Remember "acid rain"? Remember "the ozone hole"? We have solved, or greatly mitigated, environmental problems before.

SO2 emissions are still strongly trending downward globally (e.g. https://ourworldindata.org/grapher/so-emissions-by-world-reg... ). The change is especially dramatic in the US, per EPA reports. Conifers in my neighbourhood look remarkably healthier than what I recall from my childhood as a result.
